What good does it do? Everybody uses them so it must be good right? It started from the AE team drivers modifying theirs at the 2002 IFMAR world meet in Cincy... Team Magic decided to incorporate it in their G4 and lately, Ralph Burch also used it in the recent 2003 US Nats on his 705...

Anyway, as the 5th body post supports the front of the body shell better and supposedly gives better high speed stability as the body shell does not bend or warp at high speeds.

Yes I agree that the FC steering blocks somewhat gives you a better selection of rims that you can use but I find that front tires like Speedmind still rubs the steering linkage ball joints if the track has a fast sweeper. Somehow, the tires flex a little and rubs against the ball joints.

Jaco Nitro Shoes tires will fit fine in the rear as well as in the front with the stock front steering knuckles.

Now that I have the Dogde Stratus body, I could also do with a fifth body post. The body isn't so rigid where the windscreen meets the bonnet which leads to a lot of flexing.
I have previously used Alfa and Opel Vectra bodies and these bodies seemed stiff enough not to flex so much.

Cheers, Mark.

Yup... You are right about the Stratus having a softer front bonnet. I was actually trying to point out that it will not hurt even if you think you do not need it. Anything good done on the car should account for some good things. Hell, we try to strive for perfection !

Has anyone tried to use Impact centax clutch with Impact 2 speed (15/49, 18/46) and Impact rear solid axle on Impulse Pro or 705?
Any ideas? I have Impact and 835......so I wanna try those parts on my 705. If it's not a good idea, let me know.

ksrcracing, the Impact centax clutch is what we use on our Impulse if we wanted to use a Centax. On the Impulse, the only difference is that instead of the 36 mm flywheel, we have to use the 38 mm flywheel which is used on the Vector / Veteq ! The Centax II clutch on the 705 uses a 35 mm flywheel. In order to use the older Centax I clutch on a 705, I reckon that you just have to switch to the smaller flywheel (35mm) in order to avoid the flywheel scrapping on the tarmac.

The difference between the 2 speed from the Impulse Streetspec / Impulse PRO and the 2 speed from the Impact (which is the same as the Vector / Veteq) is the harder 2 speed clutch shoe springs (6626) versus the softer one found on the Impulse (801412). Also, the Impulse Streetspec / Impulse PRO uses the 801420 50T 1st gear spur instead of the 49T (9649) 1st gear spur from the Impact. The 2nd speed spur from Impulse Streetspec / Impulse PRO is only available at 47T (801417) whereas the ones from the Impact are 46T, 45T and 44T. If you use the Centax, you need to use spurs meant for the Centax to mesh properly. You can still use the 50T spur from the Impulse Streetspec / Impulse PRO but you may need to tilt the engine slightly to give it metter mesh. Also, the spurs will not line up correctly with the Centax pinions. The 705 and all the newer LC lightened 2 speed gearbox includes this heavier 6626 spring.

If you want to use the older Impact gearbox on the 705, you need to change the 2 speed main shaft and use the one from Impact as the holes will line up correctly. You need to use the older Centax I clutch in order to line the older 2 speed spurs properly. In any case, why do you want to change from new technology to old technology?

As for the Impact solid axle, you can use it direclty on the 705 without having the need to change the dogbones as they are already having the same dogbone size as the Impact / 835. If you want to use the Impact solid axle on the Impulse, you need to change the dogbones to the ones from Impact / 835 (808325) or you can even use the ones from the 705 (801323) which are a little softer as the Impact / 835 ones are made from Hudy spring steel.

Yes, most of the parts on 705 are already taken from the Impact. The 705 and the 835 shares many common parts and they are interchangeable.

Based on the link you gave, the pulleys on the Impact, the 835 and the 705 are all the same. Just make sure you when you change the internal pulleys, the ratio is correct.

I believe the only difference in the pulley mounting style is on the 18T rear side pulley of the Impact / 835. They use the MK2 aluminum pulley adaptor 9619 instead of normal 808265 aluminum pulleys adapters that is used to mount all pulleys on the 705.

Hope that helps and if you have any more questions, please fell free to shoot.

InitialD: Thanks!!!!

One last question.....Rear solid axle will do what to my 705? My 835/Impact (4WD) is great with rear solid axle....

InitialD

What body were you running with the 835/Impact? Mytsn has this to say about the solid axle on the Impulse / 705;

Replacing the rear planetary differential it allows the car to have more on power steering whilst allowing more acceleration. Another affect of this rear axle is that it removes off power steering. A perfect cure for a car with too much over steer.It is advisable to only use the axle on high grip tracks due to its driving characteristics.

I would also think that when using a rear solid axle with a one way front, the braking will be even better as the rear will not swap ends.

InitialD: I use Body Lola VDS V2 1/10 for my 835. It's high bite track......great traction.....Base on the quote.....that's what I really want....I will use rear stuff from 835 on 705 this weekend.

THANKS

About removing that diff plate and replace with plastic diff adjuster, that what I tought I've done in mine as it is makes sense (as with both plates, it would make no sense to me).

Well, after trying to rebuilt, I found that I still have to complete diff plates on both sides. Try to remove one plates (on the diff adjuster side) I see the is no way that plastic diff adjuster (mounted with 3 screws on diff gear) could hold the balls. They all falling inside... Could you please clarify further? Even in mytsn described it is an add on to your existing already smooth running diffs (if not mistaken).

Thanks

I tried the solid axle at the rear.......LOVE it......Great traction at TFB Raceway (www.tfbraceway.com)

Arun

Not good enough to beat me, HAHAHA! Just kidding, though. You did great in the 235 A-main this week. The other guys were working me as a spotter .

Proficar403: Thanks for your help....I'm trying to have my 705 to run like 835 next time.....Ready for the next weekend?....

Arun

Oh yeah, I'll be there. I have a few changes that Fernando suggested I make to my car.

Schrijver99

A you using the pulley that came with the diff adjuster? Cause i have and see no problems with mine. Are the screws turned in al the way?
